The cellar spider also goes by common names like vibrating spiders, carpenter spiders, and daddy long-legs spider. However, the name daddy long-legs is also given to other arthropods like harvestmen and crane flies. House Spider Identification Miyashita, Tadashi; Yasunori Maezono; Aya Shimazaki (March 2004).

This allows a spider to move its abdomen in all directions, and thus, for example, to spin silk without moving the cephalothorax. This waist is actually the last segment (somite) of the cephalothorax (the pregenital somite) and is lost in most other members of the Arachnida (in scorpions it is only detectable in the embryos). [ citation needed] Abdomen [ edit ] You can identify a brown spider by looking at its body shape, coloration, patterns, size of legs, and if it is smooth or hairy. In addition, spiders have identifiable two body parts, fused head and thorax (cephalothorax) and abdomen. Another identification feature is that spiders have eight legs, not six. Cellar spiders are common in houses throughout North America and are completely harmless. However, you may notice the small spider with its thin arching legs in the corner of rooms. These spiders spin messy, irregular-shaped webs high up in corners of rooms and other undisturbed places.

The cellar spider is easy to spot in homes because of its long spindly legs and tiny, egg-shaped, brown body. Although this small brown spider only measures 0.08” to 0.39” (2 – 10 mm), it has an enormous leg span of 2” (50 mm). In addition, the small spider has six eyes arranged in groups of three. Due to their brown color, the American house spider is difficult to spot indoors. Signs of these common indoor spiders are messy cobwebs in corners of window frames, ceilings, and furniture. a b "Family: Pholcidae C. L. Koch, 1850". World Spider Catalog.

Usually, harvestmen are small, with their bodies not growing more than 0.28” (7 mm) long. However, they have a characteristic large leg span, sometimes up to 6.3” (160 mm) in length. Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male spiders have specialized pedipalps that are used to transfer sperm to the female during mating. Many species of spiders exhibit a great deal of sexual dimorphism.

Other species of spiders in other countries are also called ‘common house spiders.’ The European domestic house spider ( Tegenaria domestica) is a brown spider found in Europe. It was also introduced to the US and you can find this house spider in states such as Louisiana, Oregon, Michigan, North Carolina, Washington, and New York. This article is a guide to identifying common types of brown spiders you may find in your home. Descriptions and pictures of brown-colored spiders will also help you identify a dangerous spider from a harmless one. Facts About Brown Spiders Modisimus Simon, 1893–North America, Central America, Caribbean, Germany, Seychelles, Asia, Australia, South America The large Golden silk spider (Nephila clavipes) has long legs with bright colors on the female abdomenSeeing a brown spider scurrying along the floor can be terrifying. Some brown house spiders have large dark brown bodies with long spindly legs. You might find other types of scary brown furry spiders that look like tarantulas in a basement, attic, or an outbuilding; however, they are usually completely harmless. But, of course, a large brown recluse spider can lurk in crevices and inflict a nasty bite if you get too close. Also called golden silk orb-weavers, these arachnids from the subfamily Nephilinae spin some of the most beautiful webs. Other names for this fascinating spider include ‘banana spider’ and ‘giant wood spider.’ Unlike insects, spiders don’t have any antennae or wings. Also, spiders can have up to 12 eyes; however, most have four or eight eyes.
